This is an easy to print Slingshot/Catapult.  It is a relatively slim and pocketable design made for backyard/walk around shooting with clay ammo and .6 or .7mm bands

No Supports required.  Use PLA+ or PETG for Strongest results.  5 top/bottom/shell layers at 70% Infill.  

M4 machine screws fit well with a little clearance.  I used 8-32 x 1 1/8" in the example photo, but depending on your printer, they may be too big.

I've used several versions of this without issue refining the design, but be confident you have proper layer adhesion and generally good print quality.  Print at your own risk.
